COMBINED COTTON CHOPPER AND OULTIVATOR.

Specification of Letters Patent. Application filed September 17, 1906.

Patented Feb. 5. 1907.

Serial No. 334,830.

To all, whom, it may concern..-

Be it known that we, N nw'rox K. Ronna'r- SON and Isaac WV. Jonas,citizens of the United States, residing at Sidney, in the.

county of Comanche and State of T cxas,

have invented certain new and useful Imrovements in a Combined CottonChopper and Cultivator, of which the following is a specification,reference being had therein to the accompanying drawings.

our invention relates to improvements in cotton choppers andcultivators, one of the objects being to provide a device of the char 1holding said wheel in raised or lowered position, and also means wherebysaid rideican readily raise or lower the cultivatortcctn.

Further ob ects and advantages of the in vention, as well as thestructural features by means of which they are obtained, will be madeclear by an examination of the following specification, taken inconnection with the accompanying drawings, in which Figure l is a topplan.

elevation, partly in section.

Referring to the drawings, 1 designates an axle having thereon wheels 2,and pivotally mounted on said axle by means of iollars 3, formedintegraltherewith, is an arched-shaped frame 4, in the top of which isdovetailed the rear end of a tongue 5, said tongue having an oblong slot6 tlxci'ethrough. Secured to the tongue is a cross-piece 7, provided ateach end with rectangular slots 8, through which pass depending bars 9,the upper ends of said bars being cut away to form necks l0, and havingenlarged heads ll, whereby they are held in place in said slots.Pivotally mounted on the lower ends of said bars 9 are parallel bars 12,extending rearwardly and having their rear ends 13 apertured to receivethe collars 3, by means of which they are pivotally suspended. Upon thedepending bars 9 and the rearwardly-projecting bars 12 may be adjustablymounted in the usual manner the draft connections to which thedraft-animals are attached.

Within the arched frame 4 and pivotally lower end of which Fig. 2 is aside elevation, partly in. section; and Fig. 3 is alront 1 mounted onthe axle l is an oblong frame 14,

having its rear end tapering to a point, and

. fixed on said frame is a seat support or frame 15, having a seat 16for occupancy by the rider and operator. ltotatablc in suitable bearingsin the front cross-piece of said frame l t is a shaft l7, on which isfixed a 1chopping-whecl 18, the periphery of said wheel being providedwith curved hoes or chupping-blades 12), which are preferably removablymounted in order that they may be taken off and replaced when renderedunopei ativc by wear and for the purpose of repair ing or sharpeningsame. The chopping hoes or blades 19 may be rcmovably mounted in anysuitablemanner; but, as illustrated, they have their inner ends driveninto the rim or E v ,7 periphery of the wnccl 15. ()n tne rear end ofsaid shaft is 'flXOtl a gear-wheel 20, meshing with another gear 21,fixed on the axle l to rotate therewith, the two gears comprising amiter-gear. When the machine is in motion, the revolving of the axle ctsthe gears in meticu, thcscby revolving the shaft 17 and cansing acorresponding revolution of the chopping-wheel, as will be obvious.

Pivoted at one end on the inside of the parallel longitudinal beams ofthe frame 14. is a frame 22, carrying depending arms 23, on the arefixed the cultivator blades or shares 24. These shares may be fixed onsaid arms or remcvably secured thereto, as may be found most expedientor desirable.

livctcd on the axle l is a lever 25, resembling a bell-crank lever, therear arm of which extends under the rear part of the frame 22, and theforward arm, which projects up wardly, is provided with a footrest 26,whereby said lever is operated to raise the rear end of said frame 22whenever the rider desires to raise the cultivator blades or shares 24.

Mounted on the rear end of the tongue 5 is a ratchet-segment 27,provided with a plurality of notches for the reception of aspringactuatcd latch 28, connected with the ordinary latch-handlc 29,the latch-handle being pivoted on a handle 30, which is fornted integralwith a longitudinally-extcnding lever 31, pivoted on said segnent. Theforward end of said lever is divided or forked, as at 32, and eachfork-section has an arcuate slot 32). livotally 'nountcd between theforked ends of said lever 31 by means of a pin 34, which travels in thearcuate slots 33,

isa

' scribed, a frame, an

vertical link-bar 35, which extends downwardly through the oblongopening 6 in the tongue. The lower end of this bar is cut away andprovided with an opening, which serves as a nearing for the forward endof the shaft 17, said bar being held on said shaft by means of a pin 36or by any other suitable means. Secured to the outer edge of the lowerend of the said bar 35 is a shield 37, the object of which is to preventthe dirt from coming in contact with the forward end of said shaft andwith said bearing. As a brace, and also for the purpose of securelyconnecting the tongue 5 with the arched frame 4, a curved rod 37 passesthrough said tongue, and has its ends secured to said frame 4.

In operation, when the rider desires to raise the chopping-wheel 18, sothat the hoes or chopping-blades 19 will not contact the ground, hepulls the handle 30 toward the rear of the machine, and raising theforward end of the lever 31, which in turn raises the bar 35, thuselevating the shaft 17, 011 which the chopping-wheel is mounted. Byoperating the handle 29 the latch-bar may he raised or lowered. As thislatch-bar is adapted to engage the notches on the ratchet-segment 27,said segment and the bar 28, comprising approximately a ratchet andpawl, the chopping-wheel may be held in any desired position, eitherraised or lowered, as will be apparent. By sliding the pin 34 in theslots 33 toward the rear of the machine the vertical movement of theother bar 35 is limited, and the wheel is held in more elevated positionwhen the forward end of the lever 31 is lowered to its utmost extent.

From the foregoing it is thought that the construction, arrangement, andoperation of our improved cotton chopper and cultivator will be obviousto those skilled in the art, and. further explanation is not deemed necessary.

Having thus described our said invention, what we claim as new, and.desire to secure by Letters Patent of the United States, is

1. In a machine of the character deaxle, supporting-wheels upon thelatter, a second frame pivotally mounted upon said axle, alongitudinallyextending shaft journaled in hearings upon the front endof said pivotally-mounted frame, a pinion upon the rear end of saidshaft, a gear upon said axle in DIGSll with said pinion, a portion ofsaid sha t, a lever mounted upon the first-mentioned frame and formedwith a segmental slot, means for locking said. lever against movement,and a link having its lower end provided with a hearing for the this hasthe effect of rotary cutter upon the front front end of said shaft andits upper end provided with a pin to engage the slot in said lever,substantially as described.
